SOIL-PIPE FITTING.

SFLEGIFIJTION forming part Of Letters Patent NO. 676,132, dated J une 1 l, 1 901.

Application led January 24| 1901. Serial No. 44,528. (No model.)

To all whom t may concern,.-

Be it known that I, JOSEPH P. HEENEY, ofT

Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Soil-Pipe Fittings; and

I do hereby declare that the following is a full,"

clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

This'invention relates to improvements in;

v and to facilitate the setting and the repair of the same.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a section through the wall of a building in which a soil-pipe embodying my novel fitting is positioned, showing the manner of connecting said tting. Fig. 2 is a view, partly in side elevation and partly in sect-ion, of a fitting embodying my invention. Fig. 3 is a fragmentary section of the tting, taken on the line 3 3 of Fig. 2.

As a matter of convenience I have illustrated my fitting as connected to the drainpipe of a kitchen-sink; but it isvobvious that it may be connected with closet-bowls, bathtubs, or the like; and now first referring to the general construction shown in Fig. l the letter A designates a soil-pipe, which is located in the wall A of the building behind the plastering a; B, a conventional form of sink, and C a drain-pipe connecting said sink with the soil-pipe, the said drain-pipe embodying a special fitting C', adapted for detachable connection withthe soil-pipe. Said fitting embraces a4 straight tubular part c, closed at it" '5er end by a removable plug c', and a ranch c2, which is connected with the drain-pipe C proper by means of the usual soldered joint.

D designatesa iitting, which forms a part of the soil-pipe and into which the contents of the sink B are directly discharged. Said fitting D consists of a straight tubular body portion D', made of the same diameter as the soil-pipe, and a branch D2, which communi- Lcates with the interior of the part D' through an opening cl2. Said branch D2 is adapted for connection withthe usual revent-pipe, which latter leads to the atmosphere and through which the noxious gases and fumes from the soil-pipe may be discharged into the open air. The main body D of the fitting is provided with an annular flange d at one end, adapted to surround one end of the adjacent section of the soil-pipe when assembled, and -of which the fitting forms a part when so assembled. It is plain at its other end to tit into a similarly-shaped iiange in the next adjacent section of the soil-pipe. The upper end of thel branch D2 is similarly provided with a flange cl to form a proper joint between the fitting and the next adjacent section of the revent-pipe. Said fitting D, comprising the part D and the branch D2, is made from a single integral casting. The branch D2 is so formed at its junction with the main body D as to provide at the lower end of said branch a relatively wide deep pocket D3, the greater part of which is located below the level of the communicating opening d2 between said branch and the body of the fitting. The drain pipe tting CV enters a screwthreaded opening in the lower part of the branch D2, as shown at C3, and communicates with said pocketDS. Said opening, through which the fitting C enters the pocket, is located below the level of the lower margin of the opening d2 between Vthe branch and the body fitting Desirably said tting C has screw-threaded connection with the branch D2 of the soil-pipe iitting, but may be otherwise connected thereto, as found most convenient or desirable. The lower margin surrounding the openingv cl2 constitutes a Weir over which the water discharged into the pocket D8 from the sink flows into the bodyD` of the soil-pipe fitting, and said lower margin of the opening d2 being located above the discharge opening of the tting C Ainto the branch D2 a seal is formed in said pocket, which prevents the escape of air or noxious vapor from the soil-pipe through the drainpipe Cinto the room in which the sink B is located, while permitting their escape into the atmosphere through the branch D2 and the revent-pipe attached to the flange d.

IOC

The removal of the plug c from the straight tubular part of the drain-pipe iittingV C'permits theinsertion into the soil-pipe fitting of a wire or-other suitable instrument to remove 5 from the pocket D3 any solid or semisolid matter which may have accumulated therein and aords a convenient means of access to the fitting to cleanse or repair same without tearing out plaster or removing the fitting.

One of the main or principal advantages of my construction is that the seal for preventing the escape of noxious vapors and gases from I[he soil-pipe is located entirely within the soil-pipe fitting and is made at the time 1 of casting said fitting. This construction simplifies the work of installing the connections between the drain-pipe of the sink or the' like and the soil-pipe and diminishesthe number of joints required in installing such parts. Such: diminishing of the numberof joints not only simpliiesthe work of install. ing the parts, but also greatly reducesv the chances. of leakage from broken joints. It also dispenses with the `usual S-trap or other forms of water seal, which m ust'bezconnectedi to the basin or closet and to lche soil-pipeand which must of course be revented.

Another important advantage of my invention lies in the fact that the tting is placed in the wall of the building during the. early stages of its constructionV when the soil-pipe is positioned and the other interior worksuch as plastering, hard-finish, andV trim-' need not be delayed for thel plumber, since the closet-bowl, sink, or other part may now be connected by simply soldering its proper pipe to the pipe C or directly into the threaded opening at c3 in the branch D2, as the case may be.

I-Iaving now described my invention, what I claim, and desire to secure by Letters Patent,'is asfollows:

l. As a new article of manufacture, a drainage and vent iitting and a trap in one int-egral structure adapted to be inserted into and form part of a line of soil-pipe, said itting embracing two separate chambers, one of which is adapted Yto communicate with the soil-pipe and the other with the revent-pipe.

2. A soil-pipe fitting comprising a tubular ubody forming part of a line of soil-pipe, and -an integral branch adapted for connection lwith a revent-pipel and formed at its lower end to provide a closed pocket or trap, the wall between said tubular body and branch being provided with a communicating opening and the branch member being provided below said .communicating opening with an inlet-open ling. 3. The combination with a drain-pipe lead- 'ing from a sink orV the like and a soil-pipe into which said drain-pipe discharges, of a soil-pipe iitting comprising a tubular body portion or member forming part of the line of the soil-pipe andv a branch pipe or'm'ember adapted for connection at itsupper end with la revent-pipe, and'V formedat its lower end to provide a closed pocket or trap, an opening above said trap providing communication between the body and the branch members,.the lbranch member being also provided belowthe said communicating opening. with anl aperture opening intosaid pocket andl with which a drain-pipe Vmay be connected.

4. A soil-pipe fittingA comprisinga main member which forms part of the soil-pipe,v and arevent member communicating therewith through an opening in combination with a" fitting comprising astraight tubular part adapted for engagement at one end with said revent member and provided atv its outer-end with a removable plug, and having intermediate its ends a branch adapted for connection with a drain-pipe of a sink, or the like.

In testimony thatv I claim the foregoing as my invention I afiix my signature, `in presence of two witnesses,- thisv 15th day of December, A. D. 1900. JOSEPH l. HEENEY.
